Videos: Ten things you probably didn’t know about wolf, lynx and brown bear

Biotopia has released three videos where I talk ten things you probably didn’t know about gray wolf, Eurasian lynx and brown bear, respectively. See the videos in Swedish below. English versions will be due in 2018.

I also want to take the opportunity to wish you a happy Christmas! ūüôā



Puma field work in Brazil

Ananias looks out over an area that we are soon trekking into.

In the past few weeks I’ve been out in the field in Caatinga in eastern Brazil studying the diet of a female puma. This is the first time that puma has ever been studied in this biome.

What I’ve done is I have visited sites where she has stayed for a little bit of time in order to see what she has done there. Was she eating something or just resting? The most important thing I have been wanting to find out is how much does she prey on domestic animals. This is very important because there is a lot of poaching of jaguars and pumas since they do kill and eat livestock. But how common is it? Are the farmers exaggerating or is it a real problem? And what could be done to alleviate this conflict?

There are a lot of thorny plants in Caatinga.

The field work was very difficult due to the harch environment of Caatinga. The plants are thorny and the vegetation is thick. Many plants have fish-hook thorns that would rip a normal t-shirt into pieces in a matter of hours. Also, for each step you take, there is at least one plant there to trip you. When going off-track, we progressed about 500 meters per hour. Luckily, to my help was Ananias, a local who came to be my field assistant. With his help I could use the many trails that exist which helped a lot.

Here I am investigating a goat that has been eaten by puma.

Ananias and I trekked on average ten hours per day in sweltering temperatures in this rough environment visiting these cluster sites. The temperature where we worked averaged about 30-35 degrees C in daytime. Add to this the clothes necessary to protect against the vegetation and it soon becomes very warm.

This six-banded armadillo was eaten by puma.

Some of the interesting things about working in this environment is trying the local fruits that grow ever so seldom. Running in to a mango tree after trekking a long distance was a great experience and I think that I have never tasted mangoes that sweet. There have been a lot of other interesting fruits, too, which I can’t even pronounce the names of.

Ananias has found a site used by locals to illegally trap carnivores.

There have been a lot of interesting finds in this study. This is the first time ever that this species has been studied in this biome, making it a pioneering study. I will now get down to analyzing the results. Hopefully this will lead to us being more able to protect pumas and jaguars in this area in the future – so that we can have a green planet full of life.

The project has been done as a part of Programa Amigos da Onça.


This is “cocinha”, small coconuts that you can find every here and there. Crack the shell between two rocks and you can eat the small coconut inside.

Puma study to begin

Vitória received her collar in late March. On the photo from left to right: field assistant Neto, veterinarian Gediendson Araujo, field assistant Ismael and project leader Dr. Claudia Campos. In the front row is the newest member of Programa Amigos da Onça: Vitória.

After a third and long field campaign of 45 days (!), Programa Amigos da Onça in Brazil has amazingly managed to collar a puma. This has taken a long time and the team has had to endure difficult field conditions. In total, the team has spent more than 90 days in the field in three field campaigns spanning September 2016 until now.

So, in the last days of March, a beautiful female puma named Vit√≥ria has received a GPS-collar. The name is suitable, as it means “victory”.

As a result of this success, I have now traveled to Brazil where I am currently in Petrolina preparing for field work. I am very happy that my part of the project can now get going. In the coming weeks, I will be investigating Vitória’s diet by visiting kill-sites to see her predation on wild animals and domestic animals. This will give us highly valuable information which will help us save the puma and jaguar in this area.

As a hint on the importance of the project: We can already see that Vitória has passed a farm, where the owner found tracks in the sand and, as a result, put out traps to catch her. This is unfortunately very common and shows how imperative it is to help alleviate the conflict between herders and the large carnivores. Hopefully, this is what the Program can now do.


Once again, I wish to thank everybody that has donated to the crowdfunding project! If it wasn’t for you then these next steps would not be possible.

Searching for brown bears in G√§vleborg

Something approaches.

The brown bear is the largest land-dwelling carnivore in Sweden. It can weigh up to 350 kg and feeds on a mix of berries, ants and moose calves. On Monday 3 April, I traveled up north to Gävleborg to spot for this large amazing carnivore.

Sara Wennerqvist has a hideout for brown bears and this is where I went. Joining me is Emil Nilsson from Biotopia. We park the car on a dirt road next to a stream out in the forest. As the roads have just begun thawing we cannot go the ordinary way. Instead, we pack our equipment into rucksacks and begin walking along a trail. We pretty soon come across old tracks of brown bear in the little snow that still remains. The weather is typical for April, sunny and springlike with birds chirping in the ambience and ravens floating about high up in the air.

The small windows on the hut offer a 270 degree panoramic view of the surroundings.

After trekking for two and a half kilometers we see even more bear tracks. This time they are between one to two days old. And the good thing: The hideout is just nearby.

Emil and I go into the reconstructed little hut at around 16:00, and after installing ourselves, sitting in our sleeping bags with cameras ready to use, we begin what will become a silent night, whispering and being as still as we can in order not to scare animals away. We begin spotting intensively at the surroundings through the thin glass windows of the hut.

A big brown bear, probably weighing in excess of 200 kg.

An hour goes by and we are joined by even more ravens floating around. Several woodpeckers play on the branch of a tree to our left. Apart from this, we have not seen anything.

Another hour goes by. Now the sun is very low, its beautiful warm colors blanketing the pine trees around us. I am thinking that it is quite joyful sitting here spotting. Then suddenly, like out of nowhere, I see a big dark shadow approaching cautiously from the left! Like struck by a reality check I quickly poke Emil who is looking elsewhere, giving him a sharp look and a thumbs up. He can’t see the creature from where he is sitting. Cautiously I take out my smaller camera to get ready. It is a brown bear. A big brown bear.

The male with the bright head dashes off just before it gets too dark to take photographs.

25 meters. 20 meters. It approaches slowly and cautiously. I can see that it is worried about something. Is it us? Can it see us, hear us or smell us? It does not seem to react when I take pictures or whisper to Emil, so maybe it is not us it is worried about. The bear finds some of the food that Sara has hidden underneath a rock and runs away as soon as it got what it came for.

But it soon comes back. 25 meters. 20 meters. 15 meters. 10 meters. Now Emil can see it, too. Suddenly the big bear is right in front of us – only ten meters away. They are very powerful animals. I can see its muscular body as it sniffs and searches for something to eat. We can see this bear on and off for about 30 minutes before it vanishes into the dense forest.

The hideout, with Emil’s parabolic recorder fitted by one of the hatches. It allows us to hear everything that goes on even hundreds of meters away.

Then only half an hour later there is another dark shadow approaching from the left. This one does not seem as anxious as the first. It knows where to look to find its food. Its head is surprisingly bright and it has a dark body. This bear is probably the reason the first one was so cautious. The big brown creature accompanies us on and off for the rest of the night, sometimes approaching only up to ten meters. It does not seem bothered by our presence, and it might not even notice us.

Later on, as several hours have passed and just as I am about to go to bed, Emil whispers that he can hear something through his parabolic sound recorder. He can hear steps in the undergrowth. An animal is coming closer. It is the bear coming up one last time before we call it a night, and before it is too dark to see something. By this time, all I can see is a big dark shadow, lumbering around outside of the hut. And then just like that – it is gone.
